APPARATUS FOR TREATING ORES.

SPECIFICATION forming part of Letters Patent No. 275,729, dated April10, 1883.

' Application filed October 6, 1882. (No model.)

To all whom it may concern:

Be it known that I, ELIJAH W. STOUFER, of Salida, in the county ofOhafiee, and in the State of Colorado, have invented certain new anduseful Improvements in Apparatus for Treating Ores; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being bad to the accompanying drawings, and to theletters of reference marked thereon, making apart of this specification.V I p This invention relates to certain improvements in smelting,matting, reducing, and concentrating ores; and it has for its objects toprovide certain new and improved means for carrying the above-mentionedprocesses into effect, and in the mechanical construction of the furnacetofacilitate the removal of the metal mass from the furnace should theentire contents of the furnace chill or not be drawn off through theusual openings in the walls of the furnace, as more fully hereinafterspecified. These objects I attain by the apparatus illustrated in theaccompanying drawings, in which- Figure 1 represents a verticalsectional view of my improved apparatus entire on the line :10 w of Fig.2; Fig. 2, a vertical sectional view on the line z z of Fig. 1; Fig. 3,a vertical sectional view on the line 3 y of Fig.1; Fig. 4,

a horizontal sectional view, in detail, of the front wall or doors ofthe furnace, showing a hingejoint connection between the doors and sidewalls and back of the furnace, to join the sections together and admitof'their separation.

The letter A indicates the main portion of my apparatus, which consistsessentially of a vertical water-jacket, or a series of waterchambers,setting upon an inclined waterchamber or bottom, B, and having aremovable top, G, consisting of a suitable water-chamher. Thesaidinclined bottom or water-chamber sets upon an inclined bed ofmasonry, brick-work, or other support, D, so as to maintain the walls ina vertical position. In practice I prefer to construct the walls,bottom, and top of the said main portion of my apparatus in sections,the vertical portions of which are secured by fastening devices, whichmay be formed as indicated by the letter E, (shown in Figs. 1 and 5,which represent two plates suitable device.

notched at eto interlock with each other,) or

which may be of any other construction which may prove desirable orconvenient. These sections rest upon the inclined bottom, and areconfined thereon by means of the vertical flanges F, or by any otherapproved means. The front sections of the vertical walls constitutedoors A A which are hung on hinges G, so that they can be swung back toopen the apparatus for the discharge of the contents after the treatmentof the ores has been completed, as shown in Figs. 1 and 4 of the drawings, wherein double doors A A? are made with inclined or angular abuttingor overlapping ends, in which construction the door A must first beopened. The door may be made removable and secured in place byinterlocking plates, as shown in Fig. 5, or by any other The doors donot extend quite to the front edge of the floor, leaving a space, H,through which the reduced metal may run out. Near the lower part of thesaid main part of my apparatus, at the front and rear, it is providedwith tuyeres I, through which a blast of air may be introduced at aproper time. The respective water-chambers forming the water-chambers orwater-jacket are provided withinduction and eduction ports K and L, bymeans of which a circulation of water may be kept up through the saidwater. chambers or jacket.

The letter M indicates a chamber detachably located at the top of themain portion of the apparatus, which is provided with vertical tubes N,extending from the interior of the main portion of the apparatus. up towithin a short distance of the top of the said chamber M, through whichthe products of combustion pass 0E from the interior of the part A, ofthe apparatus. From the chamber M exten d pipes O to a chamber, P,entering the same below a perforated partition, B, through which ashowerof water may be distributed. The saidcham-- her at its bottom isprovided with an outlet,- S, through which the water and condensedproducts of the volatilized ores may be drawn on. The said chamber isprovided with an escapeflue, T, through which the final products ofcombustion escape. The said chamber M is supported upon trestles U, orin any other convenient manner.

In operation the main portion of the apparatus is packed with successivelayers of fuel and ores, the same being inserted by removing the topsection and charging in the material. The combustion is then urged by ablast of air introduced through the tuyeres. The products of combustion,with the volatilized portions of the ores, pass up into the chamber atthe top of the main portion of the apparatus, where they permeate thesteam generated therein, and the volatilized metallic portions arepartially condensed and collected. The products then pass to the finalcondenser, where the metallicportions are thoroughly condensed by thewater, the smoke passing off through the eduction-tiue. The materialleft in the portion A of the apparatus when the operation is complete isremoved by opening the doors and raking orotherwise removingit from theinclined bottom. The bottom,being formed of a water-jacket casing, willwithstand great heat without being burned, and, as the bottom of thefurnace is inclined from the rear to the front and door of the furnace,may be entirely removed,and a solid mass of metal may be readily removedfrom the furnace by wedging or prying upon the sides and back walls toforce the block down the inclined floor and through the open front. Thisis often a diflicultand expensive operation in the usual form of furnacewhen the entire mass of metal cools or chills before the reduction ofthe metal is completed, and necessitates the tearing away of thepermanent walls of the furnace. The sides, bottoms, and tops of thefurnace being rectangular and made in separate water-jacketed sections,the entire apparatus may be conveniently packed or loaded fortransportation, and the entire structure may be quickly taken apart forrepairs or for removing a solid mass of metal from the interior of thefurnace. By making the chamber, as herein described, to be readilyremovable, the sedimentary matter precipitated by the condensation ofthe products of combustion may be readily removed from the chamber andthe interior thereof easily cleansed.

oftubes, N, ample exit-area isprovided, with an increased area aroundeach tube to allow ample space for condensing the products ofcombustion. As the chamber P is separated completely from the furnace,and connected to the condensing-chamber M by pipes O, the products ofcombustion are first expanded in chamber M, and, passing through thecontracted pipes O, are again expanded in the enlarged chamber P by thejets or drops of watercoming through the apertures in the partition P.The floor of the chamber P being in vclined from its ends to the middle,the matter precipitated may readily be removed through As the con-(lensing-chamber M is provided with a number the discharge-outlet S, andthe chamber may be readily cleansed.

I do not broadly claim a furnace with an inclined bottom, as such floorshave been heretofore employed in calcining and others kilns, thecontents of the furnace being removed through small or contractedopenings in the front wall of the furnace. Neither do I broadly claim afurnace for reducing metals provided with chambers for condensing theproducts of combustion from the furnace by means of steam or waterchambers and baths.

The letter V indicates inspection-openings by which the operation may bewatched.

The tuyeres in practice I prefer to provide with openings at the top orother portion, and suitable conduits by means of which chemicals may beintroduced with the blast to act in conjunction with the ores in thetreatment of the same.

Having thusdcscribed my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In an apparatus for treating ores, the main portion, consisting ofawater-jacket constructed as described, and provided with an inclinedwater-chambered bottom and removable water-chambered top, and doorshinged to the side walls of the furnace or made in a removable sectionin order to displace the entire front of the furnace, substantially asand for the purpose described.

2. The combination, with the main portion of the apparatus, of theremovable steam-generating chamber located at the top and adapted torest within and against its vertical walls, and provided with fluesextending to near its top and leading into the steam-space of saidchamber, and communicating with the main chamber, through which theproducts of combustion and volatilization pass, substantially as and forthe purposes specified.

3. The combination, with the main portion of the apparatus and thechamber connected therewith, of the final condensing-chamber ar- ELIJAHWILLSON STOUFER.
